Temperature-stable ceramic dielectric material and preparation method thereof
The invention provides a temperature-stable ceramic dielectric material and a preparation method thereof, belongs to the technical field of ceramic dielectric materials, and solves the problems of large change amplitude and low stability of the dielectric constants of existing ceramic dielectric materials within the range of -55 DEG C to 150 DEG C. According to the technical scheme, the ceramic dielectric material is composed of (Ba<0.95>Ca<0.05>)(Ti<0.9>Sn<0.1>)O3 and LiF, is obtained through a step-by-step burdening and heating method, is high in dielectric constant and low in dielectric loss, and has the X8R characteristic; the Curie peak of the stable solid solution (Ba<0.95>Ca<0.05>)(Ti<0.9>Sn<0.1>)O3 shifts to the room temperature; the sintering temperature of the system can be reduced by doping LiF; the product is compact after sintering, the dielectric constant is improved, and the dielectric loss is reduced.
本发明提供一种温度稳定型陶瓷介质材料及其制备方法，属陶瓷介质材料技术领域，解决目前陶瓷介质材料的介电常数在‑55℃～150℃范围内变化幅度大，稳定性不高的问题；技术方案为：陶瓷介质材料由(Ba0.95Ca0.05)(Ti0.9Sn0.1)O3和LiF组成，通过分步配料和升温的方法得到，该陶瓷介质材料的介电常数高、介电损耗低、同时具有X8R特征；稳定固溶体(Ba0.95Ca0.05)(Ti0.9Sn0.1)O3的居里峰向室温偏移，掺入LiF能够使系统的烧结温度降低，且烧结致密，介电常数提高，介电损耗减小。
